PULLlNG-MACHINE FOR OIL-WELLS.

Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed April 18, 1905. Serial No. 256,196.

To all whom it may concern.-

Be it known that we, WILLIAM A. WORRELL and LESLIE FISH, citizens of theUnited States, and residents of Vanburen, in the county of Grant andState of Indiana, have invented a new and Improved Pulling-Machine forOil- Wells, of which the following is a full, clear, and exactdescription.

Our invention relates to a machine for use in connection with thesinking and operation of oil-wells, although it may be used for otheranalogous purposes.

The principal objects of the invention are to provide a portable framewhich can be readily taken from one well to another, with means forpulling rods and tubes and also providing means for lowering the sameand for simultaneously lowering a tube and raising another into positionready to be lowered into a well.

Further objects of the invention will appear in the course of thesubjoined description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a machine constructed in accordance withthe principle of our invention, showing it in position fortransportation. Fig. .2 is a plan view of the same; and Fig. 3 is asectional view on the line 3 3 of Fig. 2, showing the frame in positionfor operation.

The drawings show a frame 10, provided with wheels 11, upon which it canbe moved from one well to another in an obvious Inanner. Upon the lowerpart of the frame it is provided with a shaft 12, having square ends 13,by means of which it can be turned by hand, and also provided with apair of drums 14: and 15 of different sizes. These drums are providedwith ropes or cables 16 and 17 respectively. These are designed to beattached to any desired source of energy for the purpose of operatingthe shaft. The ropes or cables may conveniently be operated by horsesand are preferably wound in opposite direction upon the drums, so thatthe unwinding of one will wind up the other. The shaft is also providedwith a ratchet-wheel 18, and a pawl 19 on the frame engages the teeththereof. The ratchet-wheel is provided with a cylindrical surface 20,upon which a brakeband 21 is applied. This brake-band is provid ed witha lever 22. The frame is provided also with two pulleys 23 and 24,mounted in an iron bracket 25. These pulleys are preferably of differentsizes and are used for different purposes. The part of the frame uponwhich these pulleys are mounted is preferably made in the form of amovable extension 26. This extension is provided with a forked end 27,in which a bar 28 on the main part of the frame is adapted to engage,and it slides in a guide 29 on the main part of the frame. On this guideis mounted a pulley 30 and on the extension an eye 31. A flexible memberin the form of a rope, chain, or cable 32 is designed to be attached tothe eye at one end and to pass over the pulley and from there back tothe shaft 12. By turning the shaft the flexible member can be wound upupon it so as to force the movable extension in an outward directionuntil it is in such position that the movable bar 28 can be applied soas to hold it, as indicated in Fig. 3. A hook 33 is provided for usewhen the device is to be transmitted, and a guide 34. is used for thedrum 16.

When the device is set up to operate, the base of it is preferablyplaced about four feet from the well and it is leaned in the directionopposite to the side upon which the wheels are located, as indicated inFig. 3. Guys 35 are then applied to hold it in the desired position. Theextension is not raised until the frame is set up and then only when itis desired to pull rods, as the machine is tall enough to pull tubingwith the extension down, and of course additional strength is securedwhen in this position. sion, the line 32 is fastened, as stated above,and the shaft turned to wind the line on the shaft. When the extensionis raised and the cross-bar 28 placed in position, the line 32 is takenoff and put aside until it is desired to lower the extension. After themachine is put in. position by means of the guys the pulling of rods isdone by a line 36, passing over the large pulley 23 and fastened to theshaft 12 between the drums and the brakewheel. The other end of the lineis fastened to the rod. A source of power, preferably a team of horses,is then connected with the line 16, and as they pull the rod or joint iselevated, while the pawl on the ratchet-wheel holds the shaft againstmotion in the wrong direction. This prevents'the dropping of the Inorder to raise the exten- 1 tube back into the well if any part of thepull ing-tackle breaks, as it stops the wheels at once. The pulling iscontinued until the joint or coupling is reached. The pawl is thenthrust up, permitting the wheels to run in the opposite direction, andthe joint is lowered onto the ground. This operation is controlled bythe brake. The joint is unscrewed from those remaining in the well. Theteam is then attached to the line 17 for turning the wheels in theopposite direction, thus lower ing the joint and winding up the line onthe large drum at the same time, this line being guided by the guide 34.The ratchet of course is not used in this lowering operation. To put thejoints back, the line used to pull out is connected with the joint andelevated by turning the shaft until the end of the joint is high enoughto enter the well again. Both the lines 16 and 17 should be wound up ontheir respective drums. The line over the pulley 24, which has been idlein pulling out the joints, is then fastened to the opposite end of theshaft and so connected as to coil in the opposite direction from theline 36. The other end of this line is then connected with a joint lyingon the ground. The joint already elevated is now lowered into the well,the speed being regulated by the brake. As this joint is lowered, theone connected with the line over the pulley 24. is elevated at the sametime by the rotation of the shaft 12. The ratchet is not used at thistime.

Having thusdescribed our invention, we claim as new and desire to secureby Letters Patent- 1. A pulling-machine for oil-wells, comprising aframe, an extension movably mounted thereon and having an eye, aflexiblemember connected with the eye, means for operating said flexible member,a pair of pulleys of different sizes mounted upon said extension, and aflexible member passing over one of said pulleys and adapted to beconnected with said means for operating the other flexible member.

2. A pulling-machine for oil-wells, comprising a movably-mountedextension having an eye, a guide for said extension, a pulley mounted onthe guide, a flexible member connected with the eye and passing over thepulley, means for drawing said flexible connection over the pulley, apair of pulleys of diflerent sizes mounted upon said extension, and aflexible member passing over one of said last-named pulleys and adaptedto be connected with said means for drawing the other flexible member.

3. A' pulling-machine for oil-wells, comprisinga frame having wheelsmounted upon one side thereof and a hook for draft purposes, a pluralityof guys for securing the framein inclined position, a shaft mounted onthe frame, two drums of difl ereut diameters mounted on the shaft, aflexible member coiled upon each drum in opposite directions, a guidefor the flexible member of one of the drums, a ratchet-wheel on theshaft, a pawl for engaging the ratchet-wheel, a brake connected with theshaft, an extension movably mounted upon the frame, said extensionhaving an eye, said frame having a guide for the extension, a pulleymounted on said guide, a flexible member connected with said eye,passing over the pulley and adapted to be connected with said shaft, aframe on the extension, a pair of pulleys of different sizes upon theframe, and a flexible member passing over one of the pulleys and adaptedto be connected with the shaft.

In testimony whereof we have signed our names to this specification inthe presenceof two subscribing witnesses.
